PIPELESS HOT-AIR FURNACE FOR BUILDINGS.

Application filed June 25,

To all whom it may concern.

Be it known that I, JUs'rUs J. WOLLEN- HAUPT, a citizen of the United States, and residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and use Improvement in Pipeless Hot- Air Furnaces for Buildings, of which the following specification is a full disclosure.

y invention relates to an improvement in a pipeless hot-air heating furnace for buildings.

An object of the invention 1s to provide a construction of pipeless furnace adapted for circulating hot air through a ma1n or predetermined port-ion of a bu ldlng, and for directing'a portion of hot a1r to a specific room or portion of the bullding, as a bath-room or bed-room.

Another object is to so correlate the general circulatin air provision and the special heating provision, that the latter will not in any material degree take space from the general heating space, or lnterfere with the circulation arrangement of the several jackets.

The features are more fully set forth in combination with the description of the accompanying drawings, forming a part of this specification, wherein Figure 1 is a central vertical section through the furnace.

Fig. 2 is a top plan view.

The furnace body unit forms the fire-box 1, combustion chamber 2 and uppermost radiator 3, of annular construction, surrounding the reduced or conical-like upper end 4 of combustion chamber 2, providing a hot-air circulating space 5, between the combustion chamberouter walls and the inner walls of said radiator. The products of combustion escape into said radiator through passage 6, circulate around the radiator and out through flue 7. Surrounding this body unit is an inner casing 8, having a conical top above the body unit. A second casing 9 surrounds the first, also having a coincident tapered upper end, and reduced diameter throat 10, a third shell 11 surrounds casing 9, also having a conical portion 12 and reduced throat portion 13. These three casings are relatively spaced to form outer, cold-air down chute 14 and the upward, hot-air chute 15, the inner casings terminating above the floor to take in air from the bottom of chute 14 and pass it upwardly between casings 8,

- 9, and between the body and casing 8. 16,

represents the inner hot-air chamber containing the heater. A single register 17 covers the concentric throats 10, 13, the cold air going down throu h the marginal portion and the heated a1r risin through the interidr central portion of said register.

While this construction adequatel heats the general run of dwellings and bulldings, it sometimes happens that some unusual condition of buildin or room arrangement renders diflicult t e heating of some particular room or portion of the building.

It will be seen that an iliary heating provision w ich would disarrange the relative spacing and arrangements of the air casings or interfere with the standard structures and installations, would be undesirable, as well as an impairment of the primary heating system efficiency.

To provide this special hot-air supply without interference with or material subtraction from the standard structure, I have conceived of the idea of utilizing the space immediately above the radiator, to take that portion of the heated air passing between the outer, upper wall of the combustion chamber, and the inner walls of. the radiator, which will not take from the air current passing upwardly around the outer walls of the radiator..-

Accordingly, I provide a hood or cone shell 18, capping the central opening formed by the annular radiator, to catch this interior hot-air current and deliver it as desired through hot-air conduit 19, which leads upwardly and outwardly, and is extended through the taper portions of the three casings.

Having described my invention, I claim:

1. In a hot-air furnace, the combination of a heater having an annular radiator head, said radiator head provided with a vertical hot-air passage centrally therethrough, a plurality of casings surrounding said heater within one another and spaced from each other, providing an outer cold-air downpassage and hot-air up-passage communicating with said outer passage at the lower a conical shell resting within the inner upward hot-air passage,

special or auxand a conductor pipe extending through said casings communicating with said dome for a direct heat distributing branch line leading from said heater.

2. In a hot-air furnace, the combination of a heater having a radiator "head, said radiator head intermediately provided with V a vertical hot-air passage therethrough, a

casing surrounding said heater providing a vertical hot-air chamber around the heater, a conical shell supported upon said radiator head within the radiator diameter as a cover for said vertical hot-air passage and forming\ a hot-air dome within said hot-air chamber non-communicative therewith above the radiator head, and a conductor pipe extending through said casing and air {chamber communicating with said hot-air dome.

In witness whereof, I hereunto subscribe my name, as attested by the two subscribing wltnesses.
